Abstract

In this article, the effect of transverse moduli of the lamina on the through-thickness hygrothermal expansion coefficients of the [± 30°]_4s,[± 45°]_4s, and [± 60°]_4s angle-ply laminates is presented. Based on the hygrothermal-elastic lamination theory, a dimensionless analysis has been used to study the influence of the various transverse elastic moduli E₂ and E₃ of a lamina on the through-thickness hygrothermal expansion coefficients in the angle-ply laminates. The results from this dimensionless analysis provide a set of general guidelines for designing and evaluating the values of through-thickness hygrothermal expansion coefficients in the angle-ply laminates to fit various environmental conditions in engineering application.
